Laxman Dewangan 0dc299a3c4 mfd: Add itps65910 wakeup support

to wakeup the system through different interrupt provided
by this device like gpios, onkey, rtc etc.

Afzal Mohammed 1e351a95b6 mfd: Make TPS65910 usable without interrupts
TPS65910 can be used without interrupts.
Hence let probe succeed in case interrupt can't be
configured and let Kernel only to complain about it

Jorge Eduardo Candelaria a2974732ca TPS65911: Add new irq definitions
TPS65911 adds new interrupt sources, as well as two new registers
to handle them, one for interrupt status and one for interrupt
masking. The added irqs are:

-VMBCH2 - Low and High threshold
-GPIO1-8 - Rising and falling edge detection
-WTCHDG - Watchdog interrupt
-PWRDN	- PWRDN reset interrupt

The code should handle these new registers only when the chip
version is TPS65911.

Graeme Gregory e3471bdc27 TPS65910: IRQ: Add interrupt controller
This module controls the interrupt handling for the tps chip. The
interrupt sources are the following:

- GPIO falling/rising edge detection
- Battery voltage below/above threshold
- PWRON signal
- PWRHOLD signal
- Temperature detection
- RTC alarm and periodic event
